MACHINE FOR PUTTING STEMS AND FEET ON GOBLET S, 86C.

SPECIFICATION forming part of Letters Patent No. 624,389, dated May 2, 1899.

Application filed August 4; 1898.

T0 (all-whom it may concern:

Be it known that I, OTTO SIGWART, a citizen of the United States, residing at Morgantown, in the county of Monongalia and State of West Virginia, have in vented certain new and useful Improvements in Machines for Putting the Stems and Feet on Goblets, dcc; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same. a

My invention has relation to machines for putting the stem and foot on goblets, &c. and

it consists in the novel construction and arrangement of its parts, as hereinafter described.

The object of the invention is to provide a machine of the nature as described, said machine being of simple and cheap construction and adapted to be duly shifted to any part During the process of producing the goblet the body of the goblet is supported at the end'of a blowpipe, and the machine is provided with a table having an opening in its center, a mold being adapted to operate over said opening.- The body of .the goblet, at the end of the blowpipe, is inserted up through the opening into the mold, and a special means is provided whereby the lower end of the blowpipe is held in its proper position. The body of the goblet being thus held in the mold, the stem or foot is molded and a descending plunger presses the same in position. The mold is so attached to the table as to prevent the possibility of making crooked stems or feet.

In the accompanying drawings, Figure l is a perspective View of the machine. Fig. 2 is a transverse sectional view of the machine, cut on the line 2 2 of Fig. 1; and Fig. 3 is a detail perspective View of the machine for holding the lower end of the blowpipe in position.

The machine consists of the table 1, said table having thelegs 2 2, the casters 3 3 beingjournaled at the lower ends of the legs 2 2. The top of the table 1 is provided with an opening 4, and immediately behind the said opening a perforation 5 is located. The upwardly-extending arm 6 is fixed in the edge Serial No. 687,733. (No model.)

thesaid plunger-rod being screw-threaded and having a tap 12, said tap being adapted to come down against the upper surface of the cross-piece 11. The ends of the cross-piece 11 are provided with perforations, which receive the perpendicular rods 13. The lower ends of said rods 13 are fixed to the outer ends-of the cross-piece 10. The upper ends of the said rods are threaded, and the jamnuts 1 1 are located on the said rods and are adapted to impinge against the upper and lower surfaces of the cross-piece 11. It will thus be seen that by manipulating the jamnuts 14 the perpendicular rods 13 may be adjusted vertically through the openings of the cross-piece 11 for the purpose of adjusting the limit of the downward movement of the plunger as said movement is terminated on the abutment of the cross-piece 10 with the lower extension 7.' When the said rods 13 are properly secured, the tap 12 is screwed down tight against the upper face of the cross-piece 11. The lever 15 is fulcnumed to the upright 6, the outer end of said lever being provided with an adjustable weight 16. The forward end of said lever is pivotally connected to the cross-piece 10, the extreme forward end of the lever extending upwardly, as at 17 in Fig. 1. Two legs 2 2 of the table 1 are connected by the brace 18. Said brace extends inwardly at the sections 19 and is provided with the central section 20, said section being provided with the elongated perforation 21. The said central section is in the vicinity of a perpendicular line dropped ICC of the table, said arm having the horizontal 1 outer end of the said arm 22 is provided with a socket 24. It will thus be seen that the said arm 22 can be shifted laterally in the perforation 21 and secured at any desired point. The mold 25 is located on the upper surface of the table 1, said mold being made in two pieces in the ordinary manner, each half of the mold being pivoted to the pin 26. The lower end of said pin 26 passes down through the perforation 5 and the halves of the mold come together just above the opening 4, the edges of the mold projecting beyond the edges of the opening, the top of the table thus supporting the mold. The upper end of the mold is perpendicularly under the plunger 9.

The machine is operated as follows: The blower forms the body of the goblet or glass on the blowpipe 27 and then inserts the body thus formed up through the opening 4 and the mold 25 is closed over the body of the goblet. The lower end of the blowpipe 27 is inserted in the socket 24 and held therein by the operator, as indicated in Fig. 3. The molten glass is then poured in the-mold 25, and by depressing the outer end of the lever. 15 the plunger 9 is brought forcibly in contact with the molten glass, and thus the end of the foot or stem is spread and at the same time the same is pressed in position upon the body of the glass. The halves of the mold 25 are then swung apart, leaving the stem in position on the goblet, and the blowpipe is removed, after which the goblet is cut from the end of the blowpipe and finished up.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1S
